3 Claims.

This invention relates to regenerator checkerworks such as are used to heat fuel gases and/or air for combustion in an open-hearth or other commercial furnaces, such as reheating furnaces, pit furnaces, glass tanks, etc., one of the objects being the production of a stable structure of high efliciency. Other objects may be inferred from the following disclosure of a specific example.

Referring to the drawings:

Figure 1 is a top plan of a checker-Work constructed according to the present invention.

Figure 2 is a cross-section from the line II-II in Figure 1.

Figure 3 is a perspective of Figure l.

Figure 4 is a top plan of one of the elements forming the checker-work shown by the above figures.

Figure 5 is a side elevation of Figure 4.

Figure 6 is an end elevation of Figure 4.

The above gures show brickwork elements each comprising an elongated form 3 having triple stud portions 4 spaced apart and from each end of the form and extending at right angles therefrom and to each other distances equal to their spacing from the ends of the form. The triple stud portions are in each instance spaced apart on the forms approximately twice their extending distances.

To form the checker-Work structure, these forms 3 are horizontally laid in layers with their ends and the outermost stud portions of adjacent forms registered. The outermost stud portions referred to are those extending at 180 degrees to each other. The middle stud portions automatically extend upwardly or downwardly when this arrangement is effected and provide support for the weight of the structure as a whole. The forms may be arranged with their lengths parallel or right angular in the various levels, as practice indicates preferable.

We claim:

1. A regenerator brickwork including a plu-v rality of elongated forms having triple stud portions spaced from their ends and extending at right angles therefrom and to each other, and

being horizontally laid with the ends of the forms and the outermost stud forms registered. Y

2. A regenerative brickwork element compris ing an elongated form having triple stud portions spaced from its ends and extending at right angles therefrom and to each other.

3. A regenerative brickwork element comprising an elongated form having triple stud portions spaced apart and from each end of the form, and extending at right angles therefrom and to each other distances equal to their spacing from said ends apart along said form.
